Hi Mickey,
The white ceramic doofer's a ballast resistor.
Reliants operate on a 9 volt system with the full 12 volts for starting. So there's an inline resistor that cuts the 12 volts from the coil down to 9 once the engine's started.
None of our trikes had them -mainly cos we didn't know about them. A couple of guys had problems with the points burning out after long high speed runs. Resistors fitted, no more problems. Your coil's probably getting hot cos it can't discharge all the energy it's producing. Fit a ballast doofer.

Don't forget it discharges the extra energy in the form of heat, so make sure you put it somewhere in the airflow.  Wink

From an online shop on Ebay? I've got to get one for my own build at some point. How much did it cost you, if you don't mind me asking?

If you can find out the resistor Value in OHM's and watts dissipated then you could probably get one from maplin's or RS.
